Given the complex number A 1 9i and B 3 0i Calculate AB

Given the complex number A = - 1 + 9i and B = 3 + 0i Calculate A/B using the complex conjugate method. Solution: The complex conjugate of B is 3 0i (choose the proper sign + - */) The equation to calculate A/B is A/B = (-1 + 9i)/(3 + 0i). (Note: Your answer should be in the form of (answer)/(answer) The answer (rounded to 3 decimal places) is A/B = + i

complex conjugate of B = 3 -i*0 = 3

A/B = (-1 +9i)/(3 ) = -1/3 +3i = -0.333 +3.00.*i
